A
CAUTION:
..
Snow can trap exhaust gases under your vehicle.
This
can cause deadly
CO
(carbon monoxide) gas
to get inside.
CO
could overcome you and kill
you. You can’t see
it
or
smell
it,
so
you
might
not
know
it
is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that
is
blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open
a
window
just
a
little
on
the side
of
the
vehicle
that’s
away from the wind. This
will
help
keep
CO
out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make
it
go
a
little faster
than just idle. That
is,
push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later
on
with your headlamps. Let the heater run for awhile.
Then, shut the engine
off
and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do
it
as little
as
possible. Preserve the
fuel
as
long as you can.
To
help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every
half hour or
so
until help comes.
